Description

Technical Field

[0001] The invention relates to the technical field of straightening raw materials for bolt production, in particular to a device for straightening raw materials for bolt production. Background Art

[0002] Steel structure bolts are high-strength bolts and are also standard parts. They have good fastening performance and are used in steel structures. Bolt production usually uses bundled steel as raw material. Before production, the existing bundled steel needs to be straightened and cut.

[0003] Existing equipment for straightening steel bundles mostly uses upper and lower rollers to press the steel bundles during transportation, then pulls the steel bundles out from the other end. However, the hardness and density of the steel structure itself are relatively high, making it difficult to deform. This makes it difficult to straighten the steel bundles, which in turn may affect the quality of the final bolts produced. To address this issue, the present invention provides a device for straightening raw materials for bolt production, making it easier to straighten steel bundles. Summary of the Invention

[0004] The purpose of the present invention is to provide a device for straightening raw materials for bolt production to solve the problems raised in the above background technology.

[0005] The top of described outer ring is provided with a toothed connecting strip, and the lower part of described toothed connecting strip is provided with the toothed connecting strip of toothed connecting strip.

[0006] Preferably, the outer wall of the pushing wheel is provided with a vertical connecting rod, the bottom of the vertical connecting rod is fixedly connected to a base, the bottom of the base is provided with a device body and fixed by bolts, and a cutting mechanism is provided on the right side of the top of the device body.

[0007] Preferably, a motor is provided on the left side of the top of the device body, a rotating shaft is connected to the output shaft of the motor, and the pushing wheel is sleeved on the rotating shaft.

[0008] Preferably, the middle portion of the pushing wheel is concave inward, the middle portion of the upper pressing wheel is convex outward, and the concave portion and the protruding portion can completely fit together.

[0009] Preferably, the heat conducting sheet and the heat conducting rod are made of graphene.

[0010] Optionally, the cutting mechanism includes a cutting base, a gantry, a second pressure cylinder, a telescopic rod, and a cutting blade. The gantry is fixedly connected to the top of the cutting base, the second pressure cylinder is arranged on the top of the gantry, the telescopic rod is arranged on the output end of the second pressure cylinder, the cutting blade is fixedly connected to the bottom end of the telescopic rod, and a knife groove is opened on the top of the cutting base. The position of the cutting blade corresponds to the position of the knife groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The bolt production raw material straightening device drives the rotating shaft to rotate through the motor, and then drives the pushing wheel to rotate clockwise. Since the friction force generated by the pushing wheel and the bundled steel when rotating is greater than the pressure of the upper pressure wheel, the bundled steel can be pushed forward by the rotation of the pushing wheel, and then passed through the straight-through pipe. The straight-through pipe is connected to the right side of the tapered straightening pipe through a thread. The inner diameter of the straight-through pipe matches the model of the bundled steel passing through, so that the bundled steel can be straightened when passing through.

[0013] The bolt production raw material straightening device, the pushing wheel rotates to push the bundling steel forward, when passing the pushing wheel and the upper pressure wheel, the bundling steel will bend, causing the bundling steel to change in properties and soften, and the contact friction between the pushing wheel and the upper pressure wheel will generate heat. The inner cavity of the pushing wheel and the upper pressure wheel are both provided with balls. At the same time, the forward transportation of the bundling steel will drive the upper pressure wheel to rotate. The rotation of the pushing wheel and the upper pressure wheel will cause the balls to rotate and collide continuously, generating a large amount of heat, and through continuous contact with the heat-conducting rod, the heat-conducting rod and the heat-conducting plate are made of graphene material. Graphene has very good thermal conductivity, which can quickly conduct the heat generated by the balls to the heat-conducting plate, and then conduct it to the bundling steel passing here. Although the bundling steel passes through this section for a short time, it can still further heat the bundling steel and increase its own temperature, which can make the bundling steel more likely to deform, and subsequent straightening and cutting are easier.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: a bolt production raw material straightening device, comprising a tapered straightening tube 1, a straight-through tube 2 is provided at the right end of the tapered straightening tube 1, a pushing wheel 3 is provided at the lower part of the left opening of the tapered straightening tube 1, a bracket 4 is fixedly connected to the top of the left side of the tapered straightening tube 1, a pressure cylinder 5 is provided on the top of the bracket 4, the output end of the pressure cylinder 5 is connected to a lifting rod 6, the bottom of the lifting rod 6 is connected to a work-type fixing frame 7, connecting rods 8 are provided on both sides of the work-type fixing frame 7, and the outer ring of the connecting rod 8 is sleeved with an upper pressing wheel 9.

[0023] Among them, the outer wall of the pushing wheel 3 is provided with a vertical connecting rod 10, the bottom of the vertical connecting rod 10 is fixedly connected to the base 11, the bottom of the base 11 is provided with an equipment body 12 and fixed by bolts, and a cutting mechanism 15 is provided on the right side of the top of the equipment body 12.

[0024] Furthermore, the cutting mechanism 15 includes a cutting base 151, a gantry 152, a second pressure cylinder 153, a telescopic rod 154, and a cutting blade 155. The gantry 152 is fixedly connected to the top of the cutting base 151, the second pressure cylinder 153 is arranged on the top of the gantry 152, the telescopic rod 154 is arranged on the output end of the second pressure cylinder 153, the cutting blade 155 is fixedly connected to the bottom end of the telescopic rod 154, and a knife groove 156 is opened on the top of the cutting base 151. The position of the cutting blade 155 corresponds to the position of the knife groove 156.

[0025] In this embodiment, before producing the bolts, the bundled steel used in the production of the bolts needs to be straightened and cut. Figure 3 As shown, when straightening the bundled steel, it enters from the left side, passes through the surface of the pushing wheel 3, and then drives the lifting rod 6 to descend through the pressure cylinder 5, and then drives the type fixing frame 7 and the upper pressure wheels 9 on both sides to descend and close to the upper surface of the bundled steel. Continuing to press down will cause the bundled steel to bend to a certain extent at the contact position between the upper pressure wheel 9, and then the motor 13 drives the rotating shaft 14 to rotate, and then drives the pushing wheel 3 to rotate clockwise. Since the friction force generated by the pushing wheel 3 and the bundled steel when rotating is greater than the pressure of the upper pressure wheel 9, the bundled steel can be pushed forward by rotating the pushing wheel 3, and then pass through the straight-through pipe 2. The straight-through pipe 2 is threadedly connected to the right side of the tapered straightening pipe 1. The inner diameter of the straight-through pipe 2 matches the model of the bundled steel passing through, so that the bundled steel can be straightened when passing through. When the model of the bundled steel required for producing bolts is changed, it is only necessary to replace the straight-through pipe 2 according to the model of the bundled steel.

[0026] After the bundled steel passes through the straight-through pipe 2, the groove on the top of the cutting base 151 is on the same horizontal line as the outlet of the straight-through pipe 2, so the bundled steel moves to the right along the groove. Then, the second pressure cylinder 153 drives the telescopic rod 154 to descend, driving the cutting blade 155 to descend to cut the bundled steel. Since the rate at which the second pressure cylinder 153 drives the telescopic rod 154 to descend is constant, the length of the cut bundled steel can be controlled to be the same.

[0027] In Example 2, a motor 13 is provided on the left side of the top of the device body 12, and a rotating shaft 14 is connected to the output shaft of the motor 13. The pushing wheel 3 is mounted on the rotating shaft 14. The middle part of the pushing wheel 3 is concave inward, and the middle part of the upper pressure wheel 9 is convex outward, and the concave part and the protruding part can be completely fitted.

[0028] In this embodiment, when the bundling steel is straightened, it enters from the left side, passes through the surface of the pushing wheel 3, and then drives the lifting rod 6 to descend through the pressure cylinder 5, and then drives the I-type fixing frame 7 and the upper pressure wheels 9 on both sides to descend and tightly contact the upper surface of the bundling steel. Continuing to press down will cause a certain degree of bending at the contact position between the bundling steel and the upper pressure wheel 9. The pushing wheel 3 rotates to push the bundling steel forward. When it passes the pushing wheel 3 and the upper pressure wheel 9, the bundling steel will bend, causing the bundling steel to change in shape and soften. At the same time, the contact and friction between the bundling steel, the pushing wheel 3 and the upper pressure wheel 9 will generate heat, so that the bundling steel is easier to be straightened.

[0029] Among them, the inner cavities of the pushing wheel 3 and the upper pressing wheel 9 are both provided with a clamping cavity 31, the inner cavity of the clamping cavity 31 is provided with a heat-conducting rod 32, and the inner cavity of the clamping cavity 31 is also irregularly distributed with balls 33. A groove is provided in the middle of the outer wall of the pushing wheel 3 and the upper pressing wheel 9, and a heat-conducting plate 34 is provided in the inner cavity of the groove. The bottom of the heat-conducting plate 34 is connected to the top of the heat-conducting rod 32, and the heat-conducting plate 34 and the heat-conducting rod 32 are made of graphene.

[0030] In this embodiment, the inner cavities of the push wheel 3 and the upper pressure wheel 9 are both provided with balls 33. The contact friction between the push wheel 3 and the upper pressure wheel 9 generates heat. At the same time, the forward conveyance of the bundled steel drives the upper pressure wheel 9 to rotate. The rotation of the push wheel 3 and the upper pressure wheel 9 causes the balls 33 to rotate and collide continuously, generating a large amount of heat. Moreover, through continuous contact with the heat-conducting rod 32, and the heat-conducting plate 34 made of graphene, which has excellent thermal conductivity, the heat generated by the balls 33 can be quickly transferred to the heat-conducting plate 34, and then to the bundled steel passing through this section. Although the bundled steel passes through this section for a short time, it can still further heat the bundled steel and increase its own temperature. This makes the bundled steel more easily deformable, making subsequent straightening and cutting easier. Moreover, because the bundled steel is softened by heating, the wear on the cutting blade 155 during cutting is also reduced.

[0031] Working principle: Before producing bolts, the bundled steel used in the production of bolts needs to be straightened and cut. Figure 3After the cam 11 is lifted up, the upper and lower ends of the cam 11 are rotated, and the upper and lower ends of the cam 12 ... The heat generated by the balls 33 is quickly transferred to the heat conducting plate 34 and then to the bundled steel passing through here. Although the bundled steel passes through this section for a short time, it can still further heat the bundled steel and increase its own temperature, which can make the bundled steel more easily deformed and make subsequent straightening and cutting easier.
